Threaded Dragon Eggs for All Occasions

This is a complete redesign of my original dragon egg, started over from scratch. It features much more uniform scale position, and no more warnings or wobbly lower layers! The threading is identical to the original profile.

There are four different versions of the egg:

• A large threaded egg with thin walls (for printing as-is or scaling up)
• A large threaded egg with thick walls (for printing as-is or scaling down)
• A small hollow egg (one piece) for printing as-is or scaling up
• A small solid egg (one piece) for printing as-is or scaling down

All four designs are included as different plates on one profile.

As designed, the large egg will hold one of McGybeer's articulated dragons. However it's a pretty snug fit, if you are making this for a small child who will want to pack it back into the egg you may wish to print the thin-walled egg scaled up a bit. A print profile for this is included - it's the “scaled to 100mm” profile.

The threads will line up the design perfectly if printed accurately. Some filaments are a bit “stickier” than others, it may take one or two opening / closing attempts to get it to move smoothly - particularly with silk PLA.

If you are printing the threaded version with a dual color / coextruded filament it is crucial that you not rotate the parts at all on the build plate, or else the colors won't line up.
